Intergalactic Pipeline

Click to Enlarge

This visible-light picture, taken by the Hubble telescope, reveals an intergalactic 'pipeline' of material flowing between two battered galaxies that bumped into each other about 100 million years ago. The pipeline [the dark string of matter] begins in NGC 1410 [the galaxy at left], crosses over 20, 000 light-years of intergalactic space, and wraps around NGC 1409 [the companion galaxy at right] like a ribbon around a package. The galaxies reside about 300 million light-years from Earth in the constellation Taurus.
